11 3/4" rotors A-Body

Might you guys know of any performance differences between the later 70's 11 3/4" brakes v the smaller 10 inchers? I understand the wheels need to be at least 15" to clear those rotors and calipers, but is there a better performing caliper for the larger rotors than, say, the 77 cordoba ones? It's only a single piston, which is why I ask.
